Presumably issued as a manual for the A.C. Gilbert glass-blowing kit; published after World War I (p. 17: "The United States and Great Britain made great strides in the manufacture of optical glass during the war"). Often misdated 1909, the year Gilbert graduated from Yale, based on the wording of the title page, "Alfred C. Gilbert, Yale University, 1909"
